In my experience you are allowed either your immediate family or one guest. However, I guess in reality it is up to the lounge personnel.
SAS web site states (my emphasis):
EuroBonus Gold members traveling on a same-day ticket with SAS, Blue1, Estonian Air and Wideroe, Star Alliance carrier are welcome to bring one guest or the immediate family in the following lounges. The guest must present a boarding card for any same day Star Alliance flight.
